Mark esp_schedule IRAM_ATTR to make it ISR safe - this complements the suspend CONT via esp_yield pattern in esp_delay for early returning from delay due to external events. In libraries/ESP8266WiFi/src/ESP8266WiFiGeneric.cpp this is done from CBs, that are called from tools/sdk/lwip/include/lwip/dns.h (#6809)
